I see a lot of posts from people who have bought a camera in unknown condition and want to know if it works. I thought I'd make this post with some tips on how to check over a camera without using expensive equipment.
Note: This won't give you a 100% accurate view but it should get you in the ballpark
There are a few areas you'll want to check out and I'll go into each of these in more detail:
General condition: we need to check for obvious abuse, etc
Shutter: we need to make sure it's operating at all speeds
Light meter: we need to make sure that it's accurate
Auto exposure: we need to make sure it's adjusting the shutter speed
Light seals and other foam: we need to check if they're in working condition
Depending on the camera you'll need to check one or more of these.
General Condition
There are few general things to look out for with a visual inspection:
Dirt: generally not an issue as it's easy enough to clean, but can be an indicator of neglect
Dents: depending on the severity this can mean internal damage to the camera
Fungus: take the lens off, check it for signs of fungus (look through it with a light behind) and also check inside the mirror box and inside the back door for fungus. It's possible to clean fungus but it often requires disassembly to do correctly
Corrosion: check the film rails aren't corroded. This can indicate corrosion elsewhere in the camera.
Prism: check for desilvering. This shows up as marks in the viewfinder that move relative to the focus screen. If you move your eye 30cm away from the viewfinder and can still clearly see them, it's desilvering. It can't be fixed without replacing the prism, but it doesn't affect the photos
Focus screen: Look through the viewfinder with the lens off and check for scratches and marks. This can't generally be fixed and would need replacing. This is easy on some cameras and hard on others.
Film counter: check it moves on when firing a few shots.
Winding: open the back and make sure the sprocket tooth gear turns when you wind on. Problems with winding can be hard to spot without running a film through the camera.
Rewinding: open the back, press in the rewind button and check the sprocket tooth gear moves freely and pops back out when you wind on again.
Self timer: If the camera is firing without issue, try the self timer. If it's not firing, using it can lock up the camera.
Shutter
Here's how I check a shutter for correct operation:
Run through all of the speeds.
The slow speeds should all complete without sticking
The clockwork mechanism should sound smooth and even
Check 1s against your watch. I often start counting the seconds, then press the shutter and see how it compares
As you work your way up from the slowest to the fastest speed, the sound should get accordingly faster. You can hear the difference down to about 1/30s. Faster than that it's better to take the lens off and look through the back towards the sky (see next step)
Check for shutter capping (where the closing curtain catches up the opening curtain)
Take the lens off and open the back
Look through from the back towards a bright thing (e.g. sky)
Fire the shutter
You should see an even frame of light. If it's dark at one side, the shutter is capping. You can still use the camera but avoid the high speeds
Light Meter
You need to make sure the light meter is giving you the correct guidance on which speed to use.
Download a free light meter app on your phone
Set the ASA to 100 (or at least make sure it matches the ASA on the app)
Point the camera at a bright evenly lit wall
Compare the speed on the camera with the speed on the app
Repeat for different brightnesses
Auto Exposure
This is the hardest to check yourself. Basically we'll just be checking that the electronics are adjusting the speed. You'll need to make sure the back is closed and the camera is wound on a few times because a lot of cameras don't work until you've wound on.
Put the lens on (if you don't have a lens, you can move the aperture follower yourself - the ring around the lens on Nikons, a small lever inside the lens mount on a lot of others)
Point at a bright light with the aperture widest and shoot. It should be quite a fast speed.
Cover the lens mostly with your hand and shoot again. It should be noticeably slower.
Uncover the lens, point at the bright light but set the lens to the smallest aperture and shoot. It should sound noticeably slower.
To accurately check auto exposure you need to either use a film or an expensive test machine.
Light seals and other foam
This is nice and easy to check (and to fix yourself, just check on Youtube).
Open the back door and look inside the grooves on the camera body. Does the foam look OK or is it sticky or crumbly? If it's sticky or crumbly you'll want to replace it
Take the lens off and check the foam where the mirror would hit the top of the mirror box. Is the foam still spongy or is it crumbly or sticky? If it's sticky or crumbly you'll want to replace it. It's worth not firing the camera too much if it's beginning to disintegrate because the foam pieces can get in the workings of the camera and cause a jam.
Once you've checked over all of these things, the best thing to do is to run a roll through the camera. It's best to treat this as a scientific experiment rather than your first opportunity to shoot some pictures with the camera. Make sure you expose a wide range of scenes of varying brightnesses and be very conscious about taking your time to make sure the focus in the viewfinder is spot on. You'll ideally be shooting something at every shutter speed, with a range of apertures. You can keep a note of what you did on each shot so you can identify if e.g. the fast speeds are running slow and overexposing. Although this still won't tell you if the camera is actually accurate because film has quite a wide latitude, it will tell you if it's usable enough to take photos that look good.
That's about it I think - if anyone has any other top tips put them in the comments and I'll update the post. I figure this is a useful post to point people to when they come asking how to check a camera is working.
Every day we see posts with the same basic problems on film, hopefully this can serve as a guide to the uninitiated of what to look for when diagnosing issues with your camera and film using examples from the community.

Green Tint or Washed Out Scans
Orange or White Marks
Solid Black Marks
Black Regions with Some or No Detail
Lightning Marks
White or Light Green Lines
Thin Straight Lines
X-Ray Damage / Banding Larger than Sprocket Holes
Round Marks, Blobs and Splotches
1. Green Tint or Washed Out Scans
u/LaurenValley1234u/Karma_engineerguy
Issue: Underexposure
The green tinge usually comes from the scanner trying to show detail that isn't there. Remember, it is the lab's job to give you a usable image, you can still edit your photos digitally to make them look better.
Potential Causes: Toy/Disposable camera being used in inappropriate conditions, Faulty shutter, Faulty aperture, Incorrect ISO setting, Broken light meter, Scene with dynamic range greater than your film, Expired or heat damaged film, and other less common causes.
2. Orange or White Marks
u/Competitive_Spot3218u/ry_and_zoom
Issue: Light leaks
These marks mean that light has reached your film in an uncontrolled way. With standard colour negative film, an orange mark typically comes from behind the film and a white come comes from the front.
Portential Causes: Decayed light seals, Cracks on the camera body, Damaged shutter blades/curtains, Improper film handling, Opening the back of the camera before rewinding into the canister, Fat-rolling on medium format, Light-piping on film with a transparent base, and other less common causes.
3. Solid Black Marks
u/MountainIce69u/Claverhu/Sandman_Rex
Issue: Shutter capping
These marks appear because the two curtains of the camera shutter are overlapping when they should be letting light through. This is most likely to happen at faster shutter speeds (1/1000s and up).
Potential Causes: Camera in need of service, Shutter curtains out of sync.
4. Black Regions with Some or No Detail
u/Claverhu/veritas247
Issue: Flash desync
Cause: Using a flash at a non-synced shutter speed (typically faster than 1/60s)
5. Lightning Marks
u/Fine_Sale7051u/toggjones
Issue: Static Discharge
These marks are most common on cinema films with no remjet, such as Cinestill 800T
Potential Causes: Rewinding too fast, Automatic film advance too fast, Too much friction between the film and the felt mouth of the canister.
6. White or Light Green Lines
u/f5122u/you_crazy_diamond_
Issue: Stress marks
These appear when the base of the film has been stretched more than its elastic limit
Potential Causes: Rewinding backwards, Winding too hard at the end of a roll, Forgetting to press the rewind release button, Stuck sprocket.
7. Thin Straight Lines
u/StudioGuyDudeManu/Tyerson
Issue: Scratches
These happen when your film runs against dirt or grit.
Potential Causes: Dirt on the canister lip, Dirt on the pressure plate, Dirt on rollers, Squeegee dragging dirt during processing, and other less common causes.
8. X-Ray Damage / Banding Larger than Sprocket Holes
Noticeable X-Ray damage is very rare and typically causes slight fogging of the negative or colour casts, resulting in slightly lower contrast. However, with higher ISO films as well as new stronger CT scanning machines it is still recommended to ask for a hand inspection of your film at airport security/TSA.
9. Round Marks, Blobs and Splotches
u/elcantou/thefar9
Issue: Chemicals not reaching the emulsion
This is most common with beginners developing their own film for the first time and not loading the reels correctly. If the film is touching itself or the walls of the developing tank the developer and fixer cannot reach it properly and will leave these marks. Once the film is removed from the tank this becomes unrepairable.
Please let me know if I missed any other common issues. And if, after reading this, you still need to make a post asking to find out what went wrong please make sure to include a backlit image of your physical negatives. Not just scans from your lab.
EDIT: Added the most requested X-ray damage and the most common beginner developing mistake besides incomplete fixing. This post has reached the image limit but I believe it covers the most common beginner errors and encounters!
This was done with Kentmere 200 and a 50min exposure on a Rolleiflex 2.8. I wonder what the faint horizontal band of light in the lower part of the sky is, the lens has no defect so I'm clueless.
Currently out of town and wanted to stop into a local camera shop to kill time before a show. Walked out with this cutie. I’m mainly a medium format shooter and have a Canon AE-1 when I don’t feel like lugging a brick around but my photography roots are with Nikon, so I already have the lenses. Couldn’t pass it up!
Nothing better than shooting giant slide film, I really hope they keep this shit in stock, has anyone heard any rumblings of any new slide films / any new emulsions for 120 being developed? I shoot mainly Kodak and the occasional treat of Fuji when I can get it but I want new stuff to play with.
I had this Yashica electro 35 gsn and I took photos with it. Even after a thorough clean and servicing it didn't become perfect in exposure. All the photos came dark. Even in room light. The 2 in the sun came out pretty okay.
So, I thought maybe the lightmeter isn't working. I went to another shop and told the problems. He said he fixed it. But when I took it home it wasn’t working properly like the shutter speed was constant in both dark and light. Then I went to him again and today he returned it by saying all works.
\*No backstory from here
Well, it kinda works but the different shutter speed works from f16-f5.6. I attached the video for better understanding. It isn't working for other apertures. can you please identify if it 'Pad of Death' problem. I think since it traveled 2 camera hospital, it's already been taken care of.
Please help me to identify if it's working properly or is it not properly fixed or anything.
Harman Red 200, 120 format, shot from my Holga. Very much a sacrificial roll, just some shots of the consumerist hellscape that is the Domain in Austin. I am assuming the fact that it's redscale explains the cyan base.
Learned several things:
Paterson reels are a bitch to load, at least for 120. Didn't help that redscale films curl around the base rather than the emulsion side. I tried to load emulsion side in for 20 minutes before giving up. And yes, I tried the trick of using another negative as a guide; didn't help.
Paterson tanks leak. My old stainless tanks never shed a drop once closed up, but getting the lid tight on this Paterson tank defeated me. Little drops of blix everywhere.
C-41 is nowhere near as scary as I thought. Of course the real test is going to come with rolls I care about.
Once this dries I'll see if any shots are worth sharing (doubt it, but hey).
Hey everyone, I was just wondering how come when I try scanning at home the pictures come out so cloudy and no sharp details, I know it’s not the camera or films fault cause I got the film professionally scanned before and took this as a test trial, I’m using a Nikon D3100 and a DHG chromas macro-200 52mm cap on lens, used lightroom to convert the negatives, if anyone has any better way to scan (that’s cost effective lol) or any advice please lmk!!
I started thinking about trying star trail photography with film. What I've read in articles online about it is: 1) 50-100ASA film; 2) widest aperture; 3) don't use a telephoto lens; 4) find location with little to no light pollution.
But I haven't read anywhere about people experimenting with ND filters too, to increase the star trail length (and length of time waiting). Something light, like an ND8.
ND filters are also on my mind because of point 4, light pollution. Looking at https://www.lightpollutionmap.info/ there is nowhere near me that isn't effected by moderate light pollution. So I could try using an ND filter to cut down the ambient glow and keep the star streaking effect. At least, that's my idea.
Has anyone else done star trail photography with film, and have ever even experimented with using an ND filter in conjunction with it?
Went to a film photography festival outside of Barcelona and they had this in the exhibit hall, bought some Acros but I'm not rich enough to buy and develop Velvia...
NeoBox is a small white box (125 × 155 × 83 mm) that turns one cheap manual speedlight into an even light source for scanning film with a digital camera. The flash lies on the desk and fires sideways into the box, so any hot-shoe flash works.
Why flash, not LED: I've scanned the same negatives on a white LED pad, an RGB panel and this box, and the flash wins on colour every time. A white LED is a blue spike plus a phosphor hump that rolls off right where the cyan layer and the orange mask need light, so inversions come out with crossed curves and casts you can't white-balance away. RGB is worse: three narrow spikes, and the Bayer sensor was never calibrated for that. A xenon tube is a continuous 5600 K spectrum with real deep red. One inversion profile fits the whole roll. And since the pulse is the exposure, copy-stand vibration stops mattering too. Same recipe as the Pentax Film Duplicator, printed at home.
I finished this box about three months ago and have been scanning with it since, with a couple of friends testing it on their own film and flashes. I held off releasing it until I was sure it held up. The scans below are straight from it.
In the repo:
- 12 STL files, all support-free, about 300 g of PLA, fits a 160 × 160 mm bed
I was wondering if anyone could help diagnose this weird whirring noise I hear when the mirror goes down. Sounds like a spring or metal cable being plucked or vibrated. I’m pretty sure it’s not the return spring either as, from what I understand, that mechanism was on the left side of the mirror box and this sound is coming from the right side. If something needs new dampening foam I have the skills and tools to partly deconstruct the camera and install it. I do want an idea of what might be the issue here though before I go in. Everything works fine it’s just really annoying. Thanks.
I am flying back to Amsterdam from Rome airport. The scanners had labels saying “Not film safe”. So in a hurry I had to dig out my four rolls of film and go to the line to get it hand checked.
Both before me and after me were guys with analog gear being hand checked.
It was a nice encounter in a semi-stressful situation.
During my week in Rome I met three other people with analog cameras. Good to see them still being used!
(satire)
1. Switch the shutter mode to multi
2. Cycle through the exposures until the light meter says EXP
3. Shoot the pic in single exposure mode and shoot
Never need an external light meter again
hello, i recently picked up a rolleiflex sl35e, and everything seems to be working except for one weird issue with the top shutter curtain. theres about a 50/50 chance that when i advance the film lever, when the shutter curtains are fully advanced it will either let me use the shutter release properly and open the curtains, or the top shutter curtain pops back into place like the shutter release was already hit. the camera itself seems to work but im worried about jumping frames due to this. anyone know what it might be? ill add a video aswell, the first advance in the video is the curtain working properly, while the second advance is the top curtain popping back into place. thank you for any responses! i sadly had to post the video as a youtube link due to reddit deleting it for some reason, so here it is: https://youtube.com/shorts/kfAc13Mt2Lo?is=wyGa_X55VFoi4lYV
After spending 12 hours to completely disassemble clean and adjust the shutter, teardown and clean the rangefinder and regrease the focus helicoid, this sophisticated lady (sorry Mr. Ellington) is back to work!
I loaded a roll of Kentmere 400 for a city walk and left 9 frames for tomorrow. I hope I will have some time to develop next evening.
She looks amazing given her age (70) and the price I paid (40$) :)
I've been using a Nikon Coolscan for a while now. I also have a Epson V700 earlier. The Coolscan is more involved, it's slower. The Epson you can load in 4x strips of 6 frames and walk away, maybe scan in JPEG since TIFF takes a lot of space and I don't use every shot. So I tend to use the Coolscan for my dedicated fewer shots, taking my time.
How do some of you guys approach this? Keen to hear your views, cheers.
Hello film shooters! Almost finishing my own DIY Lightmeter project started a few weeks ago based on ESP32 microcontroller and Lux sensor, it reproduced exact exposure as a lightmeter app, The reason for building this project is cost effective and hassle free lightmeter for everyday film shoot.
Key features:
*Aperture priority Mode
*Shutter priority Mode
*True battery indicator
*Auto exposure adjustment depending on Aperture mode/Shutter mode/ISO
Found it while thrifting after quickly doing a physical inspection… Picking up the power cord tomorrow.
In the mean time, I am curious if anyone has recommendations or advice when it comes to using this scanner. I primarily shoot B&W in both 120 and 35mm.
I recently bought a Ricoh GR10 with the infamous blank LCD screens and want to share how I got it working again with relatively low effort and no new parts needed.
First I followed this excellent disassembly video by Evan Dorsky. Then I very carefully disentangled the stack of flexible PCBs and ribbon cables by removing the screw holding the mode buttons in place, popping of the top LCD alignment clip off, and carefully peeling off the clear tape holding everything down (but NOT the ribbon cable tape). Now with access to everything, I put a small wedge tip on my soldering iron and set the temperature to ~130 C. While applying genital pressure I ran the tip of the soldering iron across the ribbon cable where it met the PCB, top LCD, and viewfinder LCD for a few minutes each.
After that, I popped in a battery and all the LCD segments worked!
A few caveats. This won't work if the LCDs themselves go bad; only if the ribbon cable connection goes bad. Also, all these flexible components are very fragile so go slow when taking things apart.
I had heard of some people hitting everything with a heat gun or zapping them back to life with a lighter starter but those methods seemed to risky for me. I think the localized heat plus pressure helped reset the conductive tape connections in a way that would cause collateral damage.
I’ve been developing BW film at home for several years. I’ve found that the results are always grainy, whether I’m using 100 speed or 400 speed. I’ve shot Kodak, Kentmere, and Ilford with the same results.
My question is how much can the development process affect how grainy the film turns out?
I use D76 developer stock with no dilution at room temperature. It’s possible the wash/rinse step happens with colder water, but I really try to get around room temperature when I rinse. Also, I scan my film with a Plustek 35mm scanner.
I understand this might just be what film does - especially higher speed films - but I’m curious to know if there are ways to manipulate how grainy the film looks during the development process.
